      These buttons were rendered using
      <strong>goog.ui.ImagelessButtonRenderer</strong>:
    </legend>
    <br/>
    These buttons were created programmatically:<br/>
    <div id="cb1"></div>
    <br/>
    These buttons were created by decorating some DIVs, and they dispatch
    state transition events (watch the event log):<br/>
    <div id="cb2">
      <!-- On FF2, if you don't enclose the contents of the button in a SPAN,
           the bold element isn't rendered.  Works on every other browser. -->

          title="Title specified in HTML">
        <span>Decorated <b>Button</b>, yay!</span>

          title="Initialized to DISABLED in HTML...">Decorated Disabled</div>
